Dill is great for pickling things like cucumbers and tomatoes. It works to bring out other herb flavorings in your cooking, though it can also overpower them if you use too much of it. Despite its very strong effect in your dishes, its flavor fades with heat, so add it at the very end.
You can make a light cucumber salad and tomato salad that uses dill. Combine cut-up tomatoes, cucumbers and a red onion with some crumbled feta cheese and dill. Drizzle over this salad a mixture of dried mint, lemon juice and olive oil.
